Dhaka: At least 10 activists of Bangladesh Chhatra League (BCL) sustained burn injuries on Saturday as a fire broke out in a running bus at Farmgate in the city.

The injured were rushed to Dhaka Medical College and Hospital.

Officer-in-charge of Tejgaon Police Station Mazharul Islam said a group of BCL activists and supporters were going to join a rally with gas balloons marking the 70th founding anniversary of BCL at Suhrawardy Udyan in the morning.

The fire might have broken out after someone lit a cigarette in the running bus around 10:30 am, he said.
